10 constructed that extra long measurements can be readily taken. i With the foregoing and other objects in view the invention consists in the combinationand arrangement of parts to be hereinafter fully described, pointed out in the claims and illustratedin the accompanying drawings which form apart of this application for patent and in which Fig. 1 is a view of the machine in side elevation.

Fig. 2 is a top plan view of the machine; Fig. 3 is an end view of Fig. 1. .Fig. 4 is a fragmentary view, enlarged, of one'end of the gage and frame.

Fig. 2. A v Fig- 8 is a fragmentary plan view of the machine.

Like. reference, characters denote corresponding parts throughout the several-views. The lead rules and cutters now in general use have their gagesprovided withteeth or notches. These teeth or notches do not'provide a true or accurate measurement due to the fact that they ar e measured off, when made, to provide approximatemeasurements only. The present lead and rule cutteris provided with a screw shaft in which the threads take the place of the notched bar of the ordi nary gage. i

This sorew-shaft is accurately cut, and the resulting measurements are necessarily absolutely correct.

.The reference numerall denotes the frame of the gauge and is operatively supported in provided with feet 2 and comprising an arch v 3' and formed with a transverse ledge 4: 50

Fig. 5 is a cross sectionon-the line 55 of Fig. 7 is asimilar view on the line 7-7 of receive the bed 5. The frame is formed, adjacent one endof the bed, with a recess 6 that registers with a similar recess 7' in the bed whereby to form a socket for the stationary blade 8. The frame and bed are'secured to-: "gether by the screws 9 and byloosening the same sh ghtly the blade 8 may beinserted'into,

adjusted, or removed from its socket; no screwsor other fastening means being necessary'for the hlade.'- v i i A bolt 10 extending through the frame, at one foot of the arch, serves as a fulcru mfor the knife bar 11 provided with the movable blade 12, said knife, bar being connected by the coil spring 13 to'the arch 3-whereby to '65 yieldingly retain said bar and blade in raised position. To lugs l lsecured to the knife bar a link 15' is secured by pin 16, said link being secured by'pin 17 to side lugs 18 riveted to the hand lever 19 fulcrumed upon the bolt 20 I to the arch of the frame, said hand lever being I formed with a spur21 against'the end of' which one end of the link 15 abuts, thus takingthe strain of operation of the handle off the pin 17. As the hand lever'is moved back and forth uponits fulcrum the movable knife and the knife bar 'oscillate, the knife passing closebeside the stationary blade and cooperating with the same to out the work in hand.

' The bed 5 is formed with a longitudinally ext-ending slot 22 that runs fromend to end andupon opposite sides of said slot the longitudinal recesses 23, 24 are for ed that are parallel to said slot.

\ A hollow gauge 25 of the same length as the bed 5 is formed with one lateral open face26 and is adaptedto slidably-rest upon the said bed, said gauge being formed with a depending rib 27 thatextends through the slot 22 and has a bar 28 secured thereto by pins 29 9 below the said slot 22,- said rib and bar serving to slidably secure the gauge to the bed. A lug 30'secured to the forward end of the gauge ridesin the said groove 23 to prevent very thin stock from slipping under the for- .95

v ward end of the gauge asit is moved over the bed. 7

A screw shaft 31 extends from end to end the'ends theree o e end zextendinghro gh cap and-head 32, 33,.

and receiving one end of the expansion coil spring 37, housed in said clamp, whereby to yieldingly retain saidlever in depressed position. The upwardly and inwardly extending end ofsaid lever is shaped toreleasably engage the threads ofthe screw shaft .to lock said gauge against sliding movement over the bed, Due to the lever 36 the screw shaft is made operable to actuate, the gauge only through oscillation or rotation of the said The uppen'f ace of the gauge is graduated 1n ems and ens, prlnters standard measurement and readable-inconnection with the :indicator 38 upon the uppermost face of the bracket 34 and indicates-the; distance between theforward or inner end of the 'auge and the cuttingsedge of the knife blade 8. i

. It willbe noted that there are two rows 38 I and-38a of ems'and ens upon the top face of the gauge, one row along each lateral edge.

'Pivotally secured to'the'closed lateral face of the gauge by the pin 39 is the extension arm 40 provided at its free end with the la erally extending integral head 41: which is formedwithydiametricailly opposed recesses- 42 and, spaced therefrom, with similarly 0pposed ribs 43,: 43, The length ofthe exten- .jsion arm from the centervofits pivot pin-39 v to the relatively outerface of the head 41 is suchthat, in the position of this arm and head shownin Fig.- 7, the head 41 is flush with :the adjacent end of the gauge and therefore the-distance from the cutting edge; of the. knife blade8 to the head 41' is the same-as the distance fromthe said knife edge to the end of the gauge.

' When the vhead 41 is turned to position nearest the knife the reading is taken from the indicator along the line of graduations contiguous thereto. This reading shows the distance fromthe' head .41 to the cutting edg of the knife. a

7 When the extension arm is'thrown 180 de- ,grees about its pivot the distance from theinner face of the head 41 to the cutting edgev of the knife 8 is exactly twice the-distance from the inner end of the gauge to the saidknife edge, provided the gauge isgthen disposed,

the maximum distance from the frame. '1.

Provided the gauge is; only slid away from the frame -1 apart of the maximum distance possiblea reading from theinner-face of the head 41 to the cutting edge of the knife 8 will be shown by the indicator 38 in connection with the relatively remote line of graduations upon the gauge. One lateral edge of the extension arm is formed with a recess 44 for engagement, in the outer position of said arm, with the pin 39 to prevent lateral or downwa d io m o s d am through gravity. The recesses 42in head 41 are to receive the rib 45, in either extreme position of said arm upon its pivot, and to provide clear ance for said rib, this rib serving as a guide for the stock being cut.

The ribs 43 of thehead travel in the groove 24 and prevent thin stock, that is being cut,

fromwedging under the head. The rib-45 is spaced inwardly uponthelbed from the knife 8 'to;provide clearance for stock that maybe laid across the bed at right angles to the rib. Fulcrumed to the under part of the frame upon the pin 46is a handle47, of springsteel,

provided with a knob 48, said handle carry- ,ing a pin 49 adapted for engagement with 1 either: of the recessed portions 50. of said a frame whereby toyieldingly keepisaid handle in either of'two adjusted positions relative to said frame. In Fig. 6 the handle. is shown in raised'position. Atthe forward end offsaid handle it engages a pin 51 that extends vertically through aperforation in the bed 5 in line with the rib 45 but spaced. therefrom. By'means of the handle 47 the pin may be projected above the surface of the bed or withdrawnto a position flush therewith. This pin serves in conjunction with the rib to guidethestock to the knife ,for the ,cutting operation.

When it is desired to slide the gage: along the bed the lower outwardly bentxend of the Z-lever 36 is manually pressed upwardly, against thetension of thespring 37, to-cause the upper inwardly bent end of the lever to release the screw shaft. The gauge may now be moved freely wto the desired :"position.

1When it is desiredtomove the shaft but the distance of one half point, or at most not more than an em, the cap andihead 32, 33 arerotated. The cap is preferablydividedoff into 1 2equal. parts by thegraduations 52; One ecomplete revolution 'ofthe screwshaft advances the gauge six pointsand, therefore,

turning t he cap a distance of one notch will jadvance the gauge one half point.

Theastockto be cut. is laidupon the bed against the rib 24 and. pin '51 as guides, one

.end of the stock abutting the head 41. When the lever 19 ismanually depressed-it c se the knives8, 12 to cut thestock.

;Whe n stock is to be trimmed or cutdown to suit the height of type it is placed transversely of thebed, the pin 51 beingdepressed, the stockabuttingthe head 41 and contiguous end of the gauge.
